“…Many river restoration efforts focus on the reestablishment of longitudinal and lateral connectivity and appearance, rather than vertical connectivity (Mendiondo, 2008;Filoso and Palmer, 2011;Sudduth et al, 2011;Kurth and Schirmer, 2014), a fact that might explain the often cited failure of river restoration with respect to ecosystem functioning (Louhi et al, 2011;Sudduth et al, 2011;Violin et al, 2011). Clearly, it is not sufficient to change the appearance of a short stretch of a stream to restore the complex interplay of riverine ecosystems and their surroundings.…”

Abstract. In this study, we investigated whether river restoration was successful in re-establishing groundwater-surface water interactions in a degraded urban stream. Restoration measures included morphological changes to the river bed, such as the installation of gravel islands and spur dykes, as well as the planting of site-specific riparian vegetation. Standard distributed temperature sensing (DTS) and novel active and passive DTS approaches were employed to study groundwater-surface water interactions in two reference streams and an experimental reach of an urban stream before and after its restoration. Radon-222 analyses were utilized to validate the losing stream conditions of the urban stream in the experimental reach. Our results indicated that river restoration at the study site was indeed successful in increasing groundwater-surface water interactions. Increased surface water downwelling occurred locally at the tip of a gravel island created during river restoration. Hence, the installation of in-stream structures increased the vertical connectivity and thus groundwater-surface water interactions. With the methods presented in this publication, it would be possible to routinely investigate the success of river restorations in re-establishing vertical connectivity, thereby gaining insight into the effectiveness of specific restoration measures. This, in turn, would enable the optimization of future river restoration projects, rendering them more cost-effective and successful.

“…Regarding the self-purification 2 process of rivers and streams, hydrological monitoring is critical for understanding the changes of pollutant concentrations in different seasons [24] [25] [26]. To assess self-purification characteristics, quali-quantitative parameters were included into the HMP of the headwaters of the main tributary rivers to Sistema Cantareira: Jaguari (1000 km 2 ), Cachoeira (392 km 2 ) and Atibainha (315 km 2 ) to find possible seasonal changes of pollutants or macronutrients (see Table 1).…”

Both Ecosystem-based Adaptation (EbA) and Payment for Ecosystem Services (PES) have a wide range of strategies that include different economic instruments for nature conservation. Although the generation and maintenance of payment for hydrologic ecosystem services (Water-PES) is expanding in Brazil, there are difficulties in the implementation of projects. Due to the complexity and non-linearity of the hydrological processes, also affecting both EbA and Water-PES goals, monitoring qualiquantitative aspects of streams have been here addressed as a useful management tool. This study presents the Hydrological Monitoring Plan (HMP) of the Water Producer/PCJ project, operating between 2009-2014, in order to: 1) evaluate the impact of project actions under water quali-quantitative aspects; and 2) promote the incorporation of HMP's elements in water resources management. HMP of the Water Producer/PCJ project has been implemented following the conditions for efficiency (baseline, long-term scale compatible with the actions of the project, in the experimental and reference watersheds). In addition, HMP is being implemented from upstream to downstream in catchments with areas ranging from 17 to 130 km 2 . This proposal favors the quantification and valuation of hydrologic services that could be assessed by ecohydrologic monitoring and modeling. Thus, we look forward to the consolidation of the Brazilian information system of water resources, the reduction of modeling uncertainties and integrated assessment of the consequences of landuse/land-cover change that strongly impact goals of EbA and Water-PES initiatives.
